Kohala Lighthouse Surf Forecast and Surf Report

Alright, Rusty here again, but in feet and inches.

So, looking at this 16-day window for the Kohala coast, it’s a tough start. We’ve got a solid run of lumpy, cross-shore winds that are just ruining the surface. From Thursday the 27th of August right up to the 8th of September, the conditions are consistently poor. That’s nearly two weeks of messy, choppy water. The water temp is sitting at a pretty normal 82°F for this time of year, so at least you’re not freezing.

The best bet on the table, and it’s a long way off, will be Kohala Lighthouse on Thursday the 10th of September. The morning is still looking a bit bumpy with some cross-onshore wind, but by the afternoon, things flip. We get a glassy surface – flat calm, no wind at all – and a solid 12ft swell from the ENE. The wave energy is huge (1972 combined energy), which means serious power, but at that size, over 8ft, this is strictly for experts. The period is 10 seconds, so it’s a decent groundswell with some push. For the crew that can handle it, that Thursday afternoon window is the standout of the whole forecast.

The morning after, Friday the 11th of September, has that glassy feel again with no wind, but the swell has dropped back to 7ft. A bit more manageable, but still heavy for most. Conditions should be clean, but the period drops to 8 seconds, meaning it’s a bit more short-period and disorganized.

Before that, it’s a long slog. The energy does build through the first week of September, hitting moderate and then strong levels (470 to 955 combined energy), but the wind is always cross-shore or cross-onshore, keeping it lumpy. No point getting excited about it until we see that glassy spell around the 10th.

Bottom line: sit tight for two weeks, then mark Thursday the 10th of September for the big, clean waves at the Lighthouse. It’s the only real standout.
